It is notable for providing a window into relations between Hittites and Greeks during the Late Bronze Age and for its mention of a prior disagreement concerning a city called Wilusa, generally identified with the archaeological site of Troy.
His particular concern was the activity of a warlord named Piyamaradu who had recently fled to Ahhiyawa-controlled territory after leading an unsuccessful rebellion in Lukka.
No surviving documents attest to the Ahhiyawan king's decision, though the subsequent decades saw an increase in Ahhiyawa control over Western Anatolia, suggesting that the appeal was rejected.
Though he scolds his Ahhiyawan counterpart for previously supporting Piyamaradu, the letter is respectful and conciliatory, and uses terms of address such as "my brother" normally reserved for rulers of major empires such as Egypt and Babylonia.
After reconsideration by Itamar Singer and Suzanne Heinhold-Krahmer in 1983, that part of the text was reinterpreted as referring to Piyamaradu and most scholars relegated Tawagalawa to a minor role in the letter.
